My C stick on my 3ds xl isn’t working right. I can push up and left easily but down and right doesn’t work correctly. So far, all the guides on the internet just show how to replace the rubber. There doesn’t seem to be a guide anywhere and I’m wondering if anyone here has done it and can show me the way.

Hi! Shouldn’t be hard. Follow this teardown guide until step 19. The C-Stick is hooked up to the button board via flex, you can clearly see it in the third picture of that step.
